I Think I Fucked Up My Chances With This Girl?

Hello, I'm currently 17 and in college as a sophomore. Right now, I'm taking 15 credits there is this one girl in my college girl is wife material and absolutely gorgeous. Anyways, in trig we talked last week during Wensday and Friday, and to be honest, the conversation was bland, but I did make her laugh a couple of times. Right now, I'm hoping to see her outside of class and hopefully she can give me some signs or just try again at conversation. Also, i found Facebook and insta, and seems to be single. On insta, she barely has any followers and only 62 people following her. Do you think I fucked up my chances or just wait longer to see? And if not, how should I approach the conversation to hopefully to get her snap.
